Open it up, check the caps on the motherboard near the processor. Then do the same to the power supply. Betting you will find some swelling.


*edit*
just looked at the model, yeah, going to be power supply (caps/fan) and MB caps. Get out your soldering iron and you patience, cause those power supplies are a biatch to work on.

or spend the 60$ and get a new one...
